OBSTRUCTION REMOVER FOR DRAIN PIPES Filed Feb. 15, 19-41 harles F. Harless Patented Aug. 5, 1941 UNITED STATES PATENT OFFICE DESTRUCTION REMOVER FOR DRAIN PIPES Charles R. Harless, Beckley, W. Va.

Application February 15, 1941, Serial No. 379,139

1 Claim.

This invention relates to sewerage obstruction removers and more particularly the water pressure type.

One of the objects of this invention resides in the provision of a sewerage obstruction remover adapted to be connected to the drain of a sink and water faucet thereof so pressure of the water will force obstructions in the drainage pipe toward and into the main sewer.

Another object of this invention resides in the particular means for retaining the remover in sealed position relative to the drainage outlet of sinks, tubs and the like.

A further object of this invention resides in the particular construction of the hose connecting elbow of the remover.

With these and other objects in view this invention resides in certain novel features of construction and arrangement of elements to be hereinafter set forth in the specification, illustrated in the accompanying drawing and pointed out in the appended claim and, while this disclosure depicts my present conception of the invention, the right is reserved to resort to such changes in. construction and arrangement of elements as come within the scope of the claim.

In the accompanying drawing forming a part of this application:

Fig. 1 is a perspective View of a sink showing the obstruction remover, forming the subject matter of this invention, disposed in operative position relative to the drain outlet thereof.

Fig. 2 is a vertical sectional view of the lower or plug end of the obstruction remover.

Fig. 3 is a detail perspective view of the elbow.

Figs. 4 and 5 are similar views of modified forms of the elbow.

In the present illustration of this invention the numeral 5 designates, in general, an obstruction remover for the drain pipes of sinks, tubs and the like and comprises a substantially coneshaped plug. 6 preferably formed of rubber or the like having an internally threaded sleeve 1, molded therein and extending therethrough for receiving an elongated pipe 8.

Threadedly secured to the opposite or free end of the pipe 8 is an elbow 9 having a nipple I0 ex-- tending therefrom toreceive one end of a flexible hose H which is provided at its opposite or free end with a suitable coupling I2 adapted to be connected to a water faucet A subsequent to disposing the plug 6 into the drain outlet, indicated by the letter B, of a sink herein designated by the letter C.

The elbow 9 is provided with a laterally extending L-shape lug l3 adapted to pivotally retain a lever l4 through the instrumentality of a screw, pin or the like I5, one end of said lever is adapted to bear beneath the faucet and pressed downwardly at its opposite end to seal the plug in the drain outlet of the sink.

In the form of elbow illustrated in Fig. 4 spaced lugs I1 are formed thereon for reception of the lever while that form of the elbow illustrated in Fig. 5 embodies a yoke l8 pivoted on the elbow so the lever can rest therein and be swung at various angles beneath the faucets of sinks or any other convenient stationary projection thereon or in range of the same.

In order to clear drainage pipes of sinks, tubs and the like of foreign obstructions with a device of'this character, it is simply necessary to insert the plug into the drainage outlet thereof, connect the hose to a faucet, press down on the lever to tightly seal the plug in the drain outlet and open the faucet to permit the pressure of the water to force the obstructions toward and into the main sewer.

Having thus described my invention what I claim and desire to protect by Letters Patent is:

An obstruction remover for drain pipes, comprising a rubber plug, an internally threaded sleeve formed in the plug, a pipe threadedly engaging the sleeve, an elbow on the free end of the pipe, a nipple on the free end of the elbow, a hose secured at one end to the nipple, a faucet coupling on the free end of the hose, a lever having its opposite ends free, and means on said elbow pivotally supporting the lever between its free ends. 7
